HYDROCARBON-VAP ORIZING BURNER.

SPECIFICATION forming part of Letters PatentNo. 657,447, dated September 4, 1900. Application filed November 16,1899, Serial No. 737,213. ("No model.)

T0 at whom it may concern..-

Be it known that we, SIMON A. PoLITsKY' and JOSEPH AGUsT, of Boston, in the county of Sufiolk and State of Massachusetts, have invented certain new anduseful Improvements in Hydrocarbon-Vaporizing Burners, of which the following is a description sufliciently full, clear, and exact to enable those skilled in the art to which it appertainsor with which it is ,mostinearly connected to make and use the same. a o I The present invention relates to hydrocarbon-vaporizing burners primarily intended for use as a heating medium; but the invention may also be utilized to advantage in illuminating apparatus.

The type of burnerto which the invention particularly appertains is that wherein oil .contained in a reservoir of convenient size for portability is. put under pressure, so as to be forced to the burner, where it is vaporized and the vapor mixed with air before reaching the place of ignition. In order to start such a burner, it is necessary to employ some means to initiate the vaporization, and it has been customary to provide a cup for alcohol or like fluid, asmall charge of which burned below the vaporizing-chamber heats the same and the oil and vapor conduits sufficiently to efiect vaporization when com- 1 munication between the reservoir and burner is set up. The scheme of preheating by a1- cohol is an objectionable feature of burners of this type because ofthejdangerattending it by reason of the necessity for pumping air into the reservoir after the preheating is under way. The use of the separate and foreign fluid is also objectionable on the score of inconvenience, itbeingfar preferable that no other fluid be required than that with which the deviceischargedasj, for example,

kerosene; but the burning of. the latter for preheating purposes in the way the alcohol is burned would be highly objectionable because of the smoke which. would result, and,

moreover, would not generate a sufficientlyhigh degree of heat. ,By thepresent invention provision is made for dispensing entirely with the use of any foreign fluid,such as alcohol, for preheatingpurposes and,moreover,

provides for burning a. charge of fluid obtained from the main supply, and that, too,

without smoke and with sufficient heat to 1 quickly accomplish the desired result. Furthermore, in the accomplishment of this result chargingof the reservoirwith pressure subsequentto preheating is avoided, so that there is no danger to be apprehended on this score in the use of the device.

.With the above-stated objects in view the invention consists in a number of novelfeatures of construction and combinations of parts, the essential elements of which are recited in the appended claims and a number of forms of embodiment of which are described hereinafter and i1lustratedintheaccompanying drawings. i i Cf said drawings,.Figure 1 representslin central vertical section an apparatus embodying features of the invention. Figs. 2

and 3 are sections taken on lines 2 2 and 3 3 of Fig. 1. Fig. 4 represents a portion of the apparatus in section, as in Fig. 1, but on an enlarged scale. t 1

The reference-letter a designates an oilreservoir of well-known general form and equipped with an air-pump b and a fillingcap 0 and having a stand-pipe d rising from its top at the center to conduct oil to the burner located at the top of the stand-pipe. A valve-casing, in theform of aunion-coupiling e, is incorporated in the stand-pipe and a suitable valve 6 arranged therein to control the flow of oil through the stand-pipe. The 1 burner at thetop of the latteris of a well-known general form, comprising an annular vaporizing-chamberf, into the bottom of which, at diametrically-opposite points, branches at of the stand-pipe enter, and out of the bottom of which at other diametricallyopposite points lead vapor-pipes f, which unite between the branch pipes d in a valve-casing f A nozzle f screws into the upper end of the valve-casing, the opening in said. nozzle flaring downwardly to form a valve-seat. The lower portion of the valve-casing is bored and screw-threaded for the engagement therewith of a stem f of aneedle-valve f g-the stem having a knob f by which to turn it, and thereby adjust the valve to regulate the roo flow. of. vapor through the nozzle. A crown a g fits over the vaporizing-chamber, with an intervening spacey to constitute a mixingchambeg'wherein the vapor and air com mingle before issuing through the perforations of the crown, where ignition takes place. The crown is preferably surmounted by a cap 9 having'an outstanding flange g 'tospreadthe flame, the usual fiaringcup g? and the burner-proper, said preheating burner being of the following descriptions An annular wick-holder h is supported around thestand-pipe and receives an annular wick h, preferably of asbestos, and a pipe k extends between said wick-holder and it a valve-casing hi, having a valve h to control the flow of oil to the wick. In order to provide for the burning of the oil thus sup; plied tothe wick with a blue flame and to prevent smoke, a. combustion-chamber of the above the ,wick to a point just below the branch (ll of the stand-pipe. A perforated cylindrical shell 1 fits around the outside of the upstanding portion of' the wick-holder,

resting against an outstanding baseportion shell air in limitedquantity reaches the wick.

" 4s i a portion just above the wick and calculatedthereof, and through the perforations of said A grooved ring or collarj rests upon the bot tjomof the wick-holder within the upstanding portion of the same and around the stand-J pipe, and a cylindrical shell j seats withinthe groove of the ring, saidshell being vertically corrugated,:so as to form passages 3' adj'acen;

,to the wick' and 'up which vapors from the oil in the wick may pass under the influence ll of thecurrents of airv induced through" the perforations-of the shell The upper of, said corrugated shell is embracedby'ap forated shell Iclyhaving a flaring lower 911' to inducethe passage of vapor-up the chan nelsj wherein such vapor commingles-w hf air, finally-issuing through the perforati otthe shell lc ywhereat it burns in blue-flam jet A sleeve'm fits snugly aroundthestan-d "and'h'as at the'top an outstandin flan'g m, extending over the topedgesolf and k and somewhatbeyond the la said flange being formed with perfor which vapor may burn.

In ope-ration," the valves ,6 and 'h heating-burner of annularform surrounding "the stand pipe' above th consisting. of anloil-h I chamber thereabove with restricted air-inlets; an oilfpipe communicating at its upper end .v withjthe' oil-holder of the preheating-burner :andat its lower end with the reservoir; a

above will quickly be brought to a high degree of heat amply sufiicientfor vaporizing purposes,whileno smoke rises fro'm'the preheaterfi The burner proper having thusbeen heated, together with the oil-conduitsleading to it, the valve ewill be opened, and the oil jrisin througli the .fstan-d-pipe' will be .iv apor: d'a i p o ss send ly-r p r'wi lp from the chamber f through". the pipes f. Such vapor in passing across fromthe nozzle f to'the mixing-chamber g takes with it sufficient air for purposes of perfect combustion at the perforationsofthe crown g.

'Itwillnowbe seen "that the constructions describedare well calculated to thoroughly fulfil the objects primarily stated. However, .it is to be understood that the invention is capable .ofiembodim nt otherwise'than as here s wn the nil-reservoir, there being incorporated'in Having thus enplained the nature of the 1 invention and described a way of construct i'ng and using" the same, though without attempting to setforth' all the forms in which 1 maybe made, or all of the modes of its use, I V it? is declared that what is claimed is;
